Announcements Releases (Server, Client & Tools)
1

Aerospike Database version 6.0.0.0-rc6 was released on April 11, 2022.

This major release contains New Features, Improvements & an Update.

  • This is a Developer Preview Release.
  • When upgrading to server version 6.0, you must wipe the drives. A modified record storage format was introduced by AER-6513, which adds protection against partially written records during an unclean shutdown.
  • For upgrading, or the unlikely event of downgrading, please refer to Special Upgrades.
  • BREAKING CHANGE: The truncate privilege is now a separate privilege and is no longer under write .
  • The batch operations capability has been made comprehensive. We now fully support batch reads, writes, deletes, and UDF commands.
  • The previously deprecated Predicate Expression API has been removed. Use Aerospike Filter Expressions (added in version 5.2).
  • Service context configuration paxos-single-replica-limit has been removed.
  • The jobs info command is now officially deprecated and will continue to be supported through a deprecation period, after which it will be removed. jobs are now redundant with the new secondary index building methods and the following new info commands:
  • The configuration parameter batch-without-digests , now defaults to true, is deprecated and will be removed in six months. Customers using clients older than a year (around the time of Server 4.9 which introduced batch-without-digests ) will now have to explicitly set the batch-without-digests configuration item to false.
  • A number of Best Practices will be checked at startup. The Best Practices can be enforced by enabling the new enforce-best-practices configuration item.
  • Use Prometheus Exporter version 1.2.1 or later to run Prometheus Exporter with this version of Aerospike Server.
